let's say, the spreadsheet has 160 rows and 12th row is empty. When I try to read the all 160 rows using the above code, it'll only read first 11 rows(until the empty row). If the spreadsheet hasn't any empty row, the code can read all 160 rows.

When I try to read next rows of the empty row, it'll return nothing. for example:

entries = first_sheet.GetRecords(50, 55) # entries is None

How can I read all rows from a Google spreadsheet which is containing empty row.
